Final answer:
A hipped roof can cause difficulty in vertical ventilation and is designed to prevent interior heat from escaping into the attic space.
Step-by-step explanation:
The type of roof that can cause significant difficulty in vertical ventilation and is designed to prevent interior heat from escaping into the attic space is a hipped roof. A hipped roof has sloping sides and all its sides slope downwards to the walls, making it difficult to install vertical vents for ventilation. The design of a hipped roof helps to trap heat inside the building, preventing it from escaping into the attic space.
